Application led September 25, 1915.

To all whom it may concern.'

Be it known that 1, EMIL F. ANDERSON, a citizen of the UnitedStates,residing at Chicago, in the county of Cook and State of illinois,have invented certain new and use ful Improvements in Bag-Filling Mechanisms, of which the following is a full, clear,

and exact specification.

My invention relates to bag filling mechanism.

lt has among its objects to provide improved mechanism for filling abag. A further obj ect of my invention is to provide improved means forholding a bag holder in its inoperative position. A still further objectof my invention is to provide improved cooperating means for holding abag and controlling the discharge port. l attain these objects by animproved construction including improved means for supporting the bagoperatively connectable in an improved manner and preferablyinterlocking with improved means controlling the dis` charge of thematerial to be bagged.

ln the accompanying drawings have shown, for purposes of illustration,one embodiment which my invention may assume in practice, the same beingshown as applied to the grain box of a stripper or harvester thresher.

1n the drawings:

Figure 1 is an end elevation pf my improvement;

Fig. 2 is a side elevation; Y

Fig. 3 is a detail view of the bag holding member.

In the construction illustrated, a grain box or reservoir 1 is providedwith a discharge outlet or opening 2 in its side wall controlled by avertically movable gate 3 reciprocable in guides 4L. This gate 3 ispivotally connected to a normally vertically disposed link 5 having alaterally inclined upper end pivoted on a depending operating lever 6pivoted at its upper end at 7 upon the upper part of the boX. Thisoperating lever 6 has a downwardly inclined laterally disposed handleportion 8 extending therefrom at a point below the pivot of the link 5.This handle portion is preferably provided with an upturned free end anda notch 9 at a point adjacent its end adapted to engage with atransverse member 1Q, preferably in the form of a roller, carriedbetween the parallel arms of a U-shaped han- Specification of LettersPatent.

dle 11 formed on and extending laterally from the bowed end of a'll-shaped bag hold ing member 12 which is pivotedat 13 on oppositesides .of the bottom ofthe opening 2 in a manner hereinafter described.As shown,the bag holding member 12 prefer'- ably conforms substantiallyto the shape of the bag mouth and is provided with a plurality `of hooksor teeth 1li thereon adapted to be punched throughthe material of thebag in such a manner that the latter may be supported thereby, theseteeth 1A preferably being disposed around the curved portion of themember 12 and also being provided on the ends ofits arms,` As shown, aplatel, preferably having a fiat upper surface and an inclined side, isalso carried upon each arm of the member 12 and entends upward therefromThese plates 15 act as bearings for the pivot 13, give very desirableclearance, and also act as limiting means, the inclined surfaces`thereof engaging with stop members 16 extending downwardly from the box1 at apoint beneath theopening 2 and thereby limiting the downwardmovement of the member 12, while their flat upper surfaces engage withthe end of the box to limit upward movement of the member 12.

Until it is desired to fill a bag, the parts occupy the compact, foldedor inoperative position shown in full lines in Fig. 1, wherein it is tobe noted that the gate 8 is down and the `bag holding member 12 is invertical position and locked therein by the engagement of the notch 9 onthe controlling member-6 with the roller 1() on the handle 11. When itis desired to fill a bag, the handle portion of the controlling member 6is raised to such an extent as to disengage the notch 9 from the roller10 but not to open the outlet 2. rlhe bag holding member 12 then dropsdown, or is lowered by gripping the handle portion 11 thereof, until itoccupies the position shown in dotted lines in Fig. l, the downwardmovement of the same being limited by engagement of the plates 15 withthe stops 16. ln this position of the parts the bag may be readilyattached to the teeth 111-. l/Vhen this has been done the handle 8 ofthe gate 8 is raised to permit grain to flow through the opening 2 intothe bag.

Attention is directed to the fact that, in my improved construction,while a bag is being filled, the controlling member 6 may be adjustedabout Vits pivot to the position shown in Fig. l and held therein in aWelllnovvn manner against an accidental returi movement due to its shapeand to the displacement of the centers. dent that this controllingmember 6 may be operated Whenever it is to open or close the outletdesiredA and that When no further bags are to be lled for the time, orit is desired to reduce the Width of themachine for any reason, the-parts may be readily returned to the compact, folded position shown infull linesin Fig. 1 and automatically locked Vtherein by pulling downthe member 6 and raising the bag holder, the curved `end of the handle 8on the controlling member 6 passing between the sides of the handle 11on the bag holder and sliding over the member l0 until the latter isseated in the notch 9 and the parts are thus rinterlocked.

While l have in this applicationspecifically described one embodimentwhich my invention may assume in practice, it is, of course, to beunderstood that this form is used for purposes of illustrationV and thatthe invention is not limited thereto but may b e embodied in otherforms.

TWhat I claim as my invention, and sire to secure by Letters Patent, is:

l. In a bag Elling mechanism, a reservoir having an outlet, outletopening and closing mechanism including an operating lever, and a bagholder pivotally supported beneath said outlet engageable with saidlever when in inoperative position and movable into operative positionupon manipulation of said lever.

2,-ln a bag'filling mechanism, a reservoir having an outlet, outletopening and closing mechanism including an operating lever, and a bagholder pivotally supported beneath said outlet'engageable With saidlever when in inoperative position and movable into operative positionupon manipulartion of said lever and prior to the opening of saidoutlet. A Y

3. ln a bag filling mechanism, a reservoir having an outlet, outletopening and closing mechanism including a pivoted operating lever havinga notch therein, and a bag holder pivoted on said reservoir be* neathsaid outlet and having a portion at one side lof its pivot engageablewith the notch in said lever when said bag holder is raised toinoperative position.

et. In a bag filling mechanism, a reser- "fvoir having an openingtherein, sliding door `mechanism for said opening, a lifting lever forsaid mechanism pivoted to said reservoir above said door and operativelyconnected to the latter, a bag holder pivoted to said reservoir beneathsaid door, and means whereby said bag holder may be locked ininoperative position by said lifting lever.

5. ln a bag filling mechanism, a reservoir having an outlet therein,outlet opening and closing means including a lever pivoted on saidreservoir above said outlet, said lever having a notch in one endthereof, and a bag holding member pivoted to said reservoir beneath saidoutlet having a vlaterally extending handle member engageable with saidnotch when said bag holding member is raised to vertical position.

6. In a bag filling mechanism, a reservoir having an outlet, outletopening and closing mechanism including a pivoted depending lever havinga curved notched end, and a bag holder pivoted on said reservoir beneathsaid outlet and having a portion at one side of its pivot automaticallyengageable with the notch in said lever as said bag holder is raised toinoperative position and releasable therefrom upon elevation of saidlever.

7. In a bag filling mechanism, a reservoir having an outlet, dependingstop inembers disposed on opposite sides of said reservoir at pointsbeneath said outlet, a bag holder pivoted to said reservoir at points infront of said stop members having depending shoulders engageable withsaid stop members and a laterally extending handle, a reciprocating doorfor said outlet, a link pivotally connected to said door, and a doorlifting lever pivotally connected to said link and pivoted to saidreservoir at a point above said pivotal connection, said lever having anangularly disposed outer end provided With a notch automaticallyengaging the handle of said bag filling member as the latter is movedtoward inoperative position.

In testimony whereof I aliix my signature.
